Arsenal were aggrieved when Alexandre Lacazette had an equaliser ruled out for offside in a contentious decision.

And that moment proved decisive as the Gunners were unable to repeat their heroics from last week’s opener against Leicester City to salvage a result.

The two teams now have three points from their first two matches. Arsenal, who were without the injured Alexis Sanchez, have not won their first two games in a Premier League season since 2009 as they suffer an early blow to their title hopes.
